Unlike most other mobile phone platforms, the phones on which
Openmoko Linux runs are designed to provide end users with the
ability to modify the operating system and software stack. The
platform is also supported by other mobile phones.[2]

This is a very different approach than that of Android (in which everything
except Linux, Webkit, and the Java language inside of Android seems
non-standard).[5]
Applications targeted for Android must be substantially rewritten
and are largely unportable. Many existing Linux desktop apps can be
easily ported to Openmoko. (However the limited computational power
and screen resolution require substantial reworking of existing
applications, in order to render them usable in a finger-oriented,
small-screen environment.)
